Abstract
Fireproof bus duct of the present utility model connects two joints or the above bus duct of two joints, make whole piece bus still can keep the running status that is energized when breaking out of fire, and it is easy for installation, insulating barrier and insulating sleeve material all adopt mica products, due to the good stability of mica, there is not the problem of aging of insulating material, thus effectively extend the useful life of bus.And mica itself has resistance to elevated temperatures, when temperature reaches 800 DEG C, still there are very high insulation property.The joint platen design of splicer both sides is rigidity material, reduces the contact resistance of joint copper bar when tightening up busbar joint, turn increases its fire resistance.In order to better meet fire-resistant demand, after two joint buses docking, joint area increase is known clearly aluminosilicate refractory fiber felt, makes joint not only play fire-resistant, resistant to elevated temperatures effect in case of fire, plays heat insulation effect simultaneously.
Description
Technical field
The utility model relates to that a kind of energy is high temperature resistant, degree of protection is high, in breaking out of fire or the normal fireproof bus duct piecing devices run can be continued when naked light burns, belong to the technical field of feed system.
Background technology
The fireproof bus duct of superior performance is having particular design requirement, the stand-by power supply in Special use place, the supply lines of generating set etc. are important, key project: as bank, TV station, data center, many places such as emphasis skyscraper are used widely, be the key technology of bus in bus duct system center tap part, the structural design of joint directly affects the runnability of bus, special even more important at refractory busbar tank systems, refractory busbar trough connection not only needs superior performance to make outside bus normally runs, also need play fire-resistant effect under fire or fire conditions.
Summary of the invention
Technical problem to be solved in the utility model is, designs a kind of fireproof bus duct piecing devices, and bus duct whole piece system can be made at high temperature, in case of fire normally to run, and easy for installation.
The technical scheme solving the employing of its technical problem is: design a kind of fireproof bus duct piecing devices, include insulating barrier, aluminosilicate refractory fiber felt, joint conductive bus bar assembly, joint pressing plate, track bolt, insulation mica sleeve pipe, joint cover plate, joint side plates; Insulation mica sleeve pipe 5 is set in and utilizes outside track bolt, and insulating barrier, joint conductive bus bar assembly, joint pressing plate have interstitial hole, be threaded onto the track bolt being set with insulation mica sleeve pipe successively, and prepackage is not tightened up, and makes splicer parts form semi-finished product.After fireproof bus duct straightway has assembled, at one end fitting joint device that straightway bus is specified, use torque spanner slightly to tighten up, make splicer be unlikely to come off.
During two joint bus docking, wherein one will save the bus that bus level inserts another joint belt lacing device, adjust distance, with torque spanner, splicer is tightened up, ensure that the contact-making surface of busbar in busbar and joint conductive bus bar assembly must be tight, and it is whether qualified with corresponding tool inspection, erection joint cover plate and joint side plates, tighten up bolt with corresponding tool, and aluminosilicate refractory fiber felt is filled up joint area, make joint be in semitight state, another joint cover plate is installed on bus slot cover board face.
Fireproof bus duct piecing devices insulating barrier of the present utility model and insulating sleeve material all adopt mica products, due to the good stability of mica, there is not the problem of aging of insulating material, thus effectively extend the useful life of bus.And mica itself has resistance to elevated temperatures, when temperature reaches 800 DEG C, still there are very high insulation property.The joint platen design of splicer both sides is rigidity material, reduces the contact resistance of joint copper bar when tightening up busbar joint, turn increases its fire resistance.In order to better meet fire-resistant demand, after two joint buses docking, joint area increase is known clearly aluminosilicate refractory fiber felt, makes joint not only play fire-resistant, resistant to elevated temperatures effect in case of fire, plays heat insulation effect simultaneously.
Fireproof bus duct of the present utility model connects two joints or the above bus duct of two joints, makes whole piece bus still can keep the running status that is energized when breaking out of fire, and easy for installation.
Accompanying drawing explanation
Fig. 1 is the outside schematic diagram of agent structure of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
Below in conjunction with accompanying drawing, the utility model is further illustrated.
In figure: 1. fireproof bus duct straightway 2. aluminosilicate refractory fiber felt 3. joint pressing plate
4. track bolt 5. insulate mica sleeve pipe 6. insulating barrier
7. joint conductive bus bar assembly 8. joint side plates 9. joint cover plate
Embodiment
As shown in the figure, fireproof bus duct piecing devices of the present utility model, include and lead aluminosilicate refractory fiber felt 2, joint pressing plate 3, track bolt 4, insulation mica sleeve pipe 5, insulating barrier 6, joint conductive bus bar assembly 7, joint side plates 8, joint cover plate 9; Insulation mica sleeve pipe 5 is set in and utilizes outside track bolt 4, insulating barrier 6, joint conductive bus bar assembly 7, joint pressing plate 3 have interstitial hole, be threaded onto the track bolt 4 being set with insulation mica sleeve pipe 5 successively, and prepackage is not tightened up, make splicer parts form semi-finished product.After fireproof bus duct straightway 1 has assembled, at one end fitting joint device that straightway bus is specified, use torque spanner slightly to tighten up, make splicer be unlikely to come off.
During two joint bus docking, wherein one will save the bus that bus level inserts another joint belt lacing device, adjust distance, with torque spanner, splicer is tightened up, ensure that the contact-making surface of the busbar of busbar and joint conductive bus bar assembly must be tight, and it is whether qualified with corresponding tool inspection, erection joint cover plate 9, with joint side plates 8, with corresponding tool, bolt is tightened up, aluminosilicate refractory fiber felt 2 is filled up joint area, make joint be in semitight state, another joint cover plate 9 is installed on bus slot cover board face.
